Configuring LLDP-MED

latitude <degrees> is the angular distance north or south from the earth equator measured
through 90 degrees. Positive numbers indicate a location north of the equator and negative
numbers indicate a location south of the equator.
resolution <bits> specifies the precision of the value given for latitude. A smaller value increases
the area within which the device is located. For latitude, enter a number between 1 and 34.
longitude <degrees> is the angular distance from the intersection of the zero meridian. Positive
values indicate a location east of the prime meridian and negative numbers indicate a location
west of the prime meridian.
resolution <bits> specifies the precision of the value given for longitude. A smaller value increases
the area within which the device is located. For longitude resolution, enter a number between 1
and 34.
altitude floors <number> is the vertical elevation of a building above the ground, where 0
represents the floor level associated with the ground level at the main entrance and larger values
represent floors that are above (higher in altitude) floors with lower values. For example, 2 for the
2nd floor. Sub-floors can be represented by non-integer values. For example, a mezzanine
between floor 1 and floor 2 could be represented as 1.1. Similarly, the mezzanines between floor 4
and floor 5 could be represented as 4.1 and 4.2 respectively. Floors located below ground level
could be represented by negative values.
resolution <bits> specifies the precision of the value given for altitude. A smaller value increases
the area within which the device is located. For floors resolution, enter the value 0 if the floor is
unknown, or 30 if a valid floor is being specified.
altitude meters <number> is the vertical elevation in number of meters, as opposed to floors.
resolution <bits> specifies the precision of the value given for altitude. A smaller value increases
the area within which the device is located. For meters resolution, enter a value from 0 to 30.
<Datum> is the map used as the basis for calculating the location. Specify one of the following:
•
wgs84 – (geographical 3D) – World Geodesic System 1984, CRS Code 4327, Prime Meridian
Name: Greenwich
•
nad83-navd88 – North American Datum 1983, CRS Code 4269, Prime Meridian Name:
Greenwich; The associated vertical datum is the North American Vertical Datum of 1988
(NAVD88). Use this datum when referencing locations on land. If land is near tidal water, use
nad83-mllw (below).
•
nad83-mllw – North American Datum 1983, CRS Code 4269, Prime Meridian Name:
Greenwich; The associated vertical datum is mean lower low water (MLLW). Use this datum
when referencing locations on water, sea, or ocean.
